There are two wires attached to the socket. One goes to the tongue at the
bottom of the socket and the other to the screw shell. Sometimes these wires
are riveted to the socket, and a rivet loosens up. This would require
replacing the socket. Sometimes the wires are attached by screw terminals
which can come loose. This would require retightening. Sometimes the tongue
at the bottom of the socket becomes depressed, and the lamp doesn't reach it
to make contact. This would require carefully prying it back up. At some
location in the fixture, all 10 wires come together and are spliced to the
feed wires. Its possible one of the wires for the dead socket came loose
here, and would need to be reconnected

My D.R. ceiling fixture has 5 sockets. When changing bulbs.
I noticed that one socket did not work. I shut off wall switch; tried
unsuccessfully to look inside socket; swabbed it out with old
toothbrush *; sprayed with Cramolin (used for audio equipt),
but no luck.

Any educated guesses on why one of 5 would have crapped out?

And what is best approach to reviving it?

TIA
